SIT9121AI-2B2-33E100.000000G - SiTime

SIT9121AI-2B2-33E100.000000G Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  SiTime recommends a 4-layer PCB with a solid ground plane, and to keep the oscillator away from high-frequency signals and noise sources. A good layout should also minimize the distance between the oscillator and the crystal, and use a low-impedance path for the crystal connections.
• How do I ensure the oscillator starts up reliably in my application?
  To ensure reliable startup, SiTime recommends a power supply ramp-up time of at least 1 ms, and a voltage supply within the recommended operating range. Additionally, the oscillator should be decoupled with a 0.1 uF capacitor and a 10 uF capacitor in parallel.
• What is the maximum operating temperature range for this oscillator?
  The SIT9121AI-2B2-33E100.000000G oscillator is rated for operation from -40°C to +85°C, but it can be customized for extended temperature ranges upon request.
• How do I adjust the frequency of the oscillator?
  The frequency of the SIT9121AI-2B2-33E100.000000G oscillator is fixed at 100 MHz, but SiTime offers a range of frequencies from 1 MHz to 137 MHz. If a custom frequency is required, contact SiTime for a custom part number.
• What is the typical current consumption of this oscillator?
  The typical current consumption of the SIT9121AI-2B2-33E100.000000G oscillator is 15 mA, but this can vary depending on the specific application and operating conditions.
